NAME
       AppConfig::Getopt - Perl5 module for processing command line arguments
       via delegation to Getopt::Long.

SYNOPSIS
	   use AppConfig::Getopt;

	   my $state  = AppConfig::State->new(\%cfg);
	   my $getopt = AppConfig::Getopt->new($state);

	   $getopt->parse(\@args);	      # read args

OVERVIEW
       AppConfig::Getopt is a Perl5 module which delegates to Johan Vroman’s
       Getopt::Long module to parse command line arguments and update values
       in an AppConfig::State object accordingly.

       AppConfig::Getopt is distributed as part of the AppConfig bundle.

DESCRIPTION
       USING THE AppConfig::Getopt MODULE

       To import and use the AppConfig::Getopt module the following line
       should appear in your Perl script:

	   use AppConfig::Getopt;

       AppConfig::Getopt is used automatically if you use the AppConfig mod-
       ule and create an AppConfig::Getopt object through the getopt()
       method.

       AppConfig::Getopt is implemented using object-oriented methods.	A new
       AppConfig::Getopt object is created and initialised using the new()
       method.	This returns a reference to a new AppConfig::Getopt object.
       A reference to an AppConfig::State object should be passed in as the
       first parameter:

	   my $state  = AppConfig::State->new();
	   my $getopt = AppConfig::Getopt->new($state);

       This will create and return a reference to a new AppConfig::Getopt
       object.

       PARSING COMMAND LINE ARGUMENTS

       The "parse()" method is used to read a list of command line arguments
       and update the state accordingly.

       The first (non-list reference) parameters may contain a number of con-
       figuration strings to pass to Getopt::Long::Configure.  A reference to
       a list of arguments may additionally be passed or @ARGV is used by
       default.

	   $getopt->parse();			   # uses @ARGV
	   $getopt->parse(\@myargs);
	   $getopt->parse(qw(auto_abbrev debug));  # uses @ARGV
	   $getopt->parse(qw(debug), \@myargs);

       See Getopt::Long for details of the configuartion options available.

       A Getopt::Long specification string is constructed for each variable
       defined in the AppConfig::State.	 This consists of the name, any
       aliases and the ARGS value for the variable.

       These specification string are then passed to Getopt::Long, the argu-
       ments are parsed and the values in the AppConfig::State updated.

       See AppConfig for information about using the AppConfig::Getopt module
       via the getopt() method.
